Display device and method of manufacturing the same

A method of manufacturing a display device, the method comprising:

• providing a thin film transistor in a light-emitting area of a substrate;
• providing a first organic material layer covering the thin film transistor, and patterning the first organic material layer to provide a first insulating layer;
• providing a pixel electrode electrically connected to the thin film transistor;
• and
• providing a second organic material layer covering the first insulating layer and the pixel electrode, and patterning the second organic material layer to provide a second insulating layer which defines the light-emitting area,
• wherein
• the first insulating layer comprises:
• a first area corresponding to the light-emitting area, and
• a second area disposed outside the light-emitting area, the second area having a thickness which is less than a thickness of the first area,
• within the light-emitting area, the second insulating layer covers edges of the pixel electrode and covers external lateral surfaces of the first area of the first insulating layer, and
• a height of the second insulating layer decreases along a direction from the first area to the second area.
